66AK2H U-boot booting from NAND

HI,

Thanks for your reply,

Have you added the NAND configs (like CONFIG_NAND_DAVINCI) in K2H EVM defconfig file located at "u-boot-keystone/include/configs/ks2_evm.h" ?

Yes

What is your MCSDK version ?

mcsdk_linux_3_00_03_15 

This function "init_async_emif" should get callled in the following file.
u-boot/board//ti/ks2_evm/board_k2hk.c

Drivers location: (it should built *.o)
drivers/mtd/nand/davinci_nand.c

I have called this function in board_k2hk.c and also while building i could davinici_nand binary generated.

Are you working on custom board ?

Did you use different NAND flash on your board ?

yes ours is customized board, but the flash is connected to 66AK2H in similar way that is connected in K2H EVM schematic. We are using the same flash chip

(MT29F4G08ABBDAHC-IT)  used in k2h EVM .

Since  Flash is same in both evm kit as well as in our customized board,i dint change in any of timings configuration.

I am using uboot version (uboot-keystone-2013.01) and same is working when ported in EVM kit and not in our customized board.

Please suggest,

Thanks.
Can you please attach the log which you used to build the u-boot (and u-boot build log) ?
Also attach the .h file of "include/configs/k2hk_evm.h"

Hi,

Hi,

Please find the attachment,

I imported the project nand writer and try  to write sample application from DDR to nand memory. Project crashes with message "Bad block # detected, skipping block ... "

arm-nand.txt

Hi Titus,

Any inputs regarding NAND.

I tried the nand writer and the platform test case but it shows bad block in all the sector. I have also attached log in my previous post.

Please guide us to sort out this issue

Hi Titus,

Hope the below information could help you to suggest us some ideas to sort it out.

As you said, i downloaded the latest u-boot from site

and in initial when i ported the u-boot, the result looks same . Nand was not detecting properly.But when i added delay after reset command in nand.c ,i could able to see 512MB NAND flash.

Query:

The u-boot source which i am using is same as the one ported in the your ti EVM Kit. In EVM kit, without any delay it is able to detect nand  but in our board for same chip , we have added delay to detect it.Why this delay difference ?

The only difference with your and our schematic for NAND section is wait state. You have used wait_0 and we have connected to wait_1. Will this makes any difference ?

Even if nand is detected, i am not able to perform any read or write operation to NAND, You could see the below screenshot,

Vidya,

Can you see if the Uboot source is setting extended Wait polarity using the EMIF16 AWCRR register. The EMIF16 User guide mentions that programming the correct wait state is important. Here is text from the EMIF16 user guide.

A chip select can be mapped to either of the two pins EMIFWAIT[1:0] by appropriately setting the CS2-5_WAIT fields in the Async Wait Cycle Config Register (AWCCR). It is also important to correctly set the active polarity of the EMIFWAIT pins by programming the WP0-1 bits in the AWCCR. A ‘0’ means EMIF16 will insert wait cycles when EMIFWAIT is low, and sampled high when polarity is set to 1.

This would imply that you need to modify the code to use wait1 instead of wait0 and make sure that the signal is driven high. Since the EVM is using WAIT0, I suspect that they are driving the wait state low on wait1.

Regards,
Rahul

Hi Titus,

I tried the both commands but still issue is same. I am not able to write to NAND memory.

I tried to read data from NAND to DDR location(0x80000000)  and i used below command,

U-Boot# nand read.raw 80000000 0 1

NAND read:  2112 bytes read: OK

and i could see the data in ddr memory.

Similarly i tried to write data from DDR to NAND memory using below command ,

U-Boot# nand write.raw 0x80000000 0 1

NAND write: WARNING in drivers/mtd/nand/nand_base.c line 1027
raw_access: error at offset 0, ret -5
 2112 bytes written: ERROR

I could see the data in NAND using nand dump command but the data looks corrupted in between ,

U-Boot#

Even if it writes, nand write command shows error at the end. Why is this happening. Any command syntax issue or nand is not configured properly ?

Please suggest,

Hi Rahul,

I checked the register AWCRR in u-boot once nand initalized,

Its shows value 0xf0040080  which is been set wait state 1 for CS3_WAIT and with default MAX_EXT_WAIT and polarity state.

From U-boot command , i changed the value to 0xf0010080  which sets wait state 1 for CS2_WAIT. But still i faces issue in read and write.

Hi,

Please find the attachment,

Have you added the Inverted IC on EMIF OE pin as EVM used (U69) to solve the EMIF read/write issue ?

I understand U69 inverted IC in EVM is meant to access EMIF16 through edge connector(CN3).

Is this inverter IC any way related in accessing NAND FLASH ?

Still you are not able to get the correct manufacturer ID and product ID ?

I am able to read the manufacturer and product ID after adding delay in nand.c file. Just added a printf as a delay.

Hi,

Are you seeing any activity on the CS when you run the uboot ?

Yes.I am able to see CS when uboot tries to read or write to the nand. U-boot is able to successfully prints the NAND information and its size 512MB. which confirms NAND CS.

If possible, please share the NAND portion of your custom board schematics.

I have attached the EMIF to NAND connection. Please find the attachment,

Please let us know if any changes to be done in HW,

Hi,

Yes. Wait signal was the only change in both the schematic. I checked the nand behavior in both wait signal condition and the behavior looks same.

Nand write and read is able to perform but it shows error on completion .

nand write.raw 0x80000000 0 0xFF

NAND write: WARNING in drivers/mtd/nand/nand_base.c line 1027
raw_access: error at offset 0, ret -5
 538560 bytes written: ERROR

This cannot be issue in assembly. Bcoz we are able to access the NAND and perform read/write but not to completely. 

Both screen shot shows error at offset 0 but it has written 538560 bytes.

Please suggest,

Hi,

We have used NAND chip of different part no.(MT29F1G08ABBDAHC-IT) in other custom boards and its working.

We have connected wait state 0 to Nand chip as per your suggestion but still it dint help.

Can you tell us how to read and write to the full Nand chip through u-boot command.

I suspect writing to 0th location is creating error message.

Hi ,

Sorry for delay response,

As Senthil said, there might be defect in nand device.So we replaced the chip completely and placed new nand chip of same part number.

Even in this case with wait state1 , we were not able to perform read and write. Then , we connected R/B signal to  wait state 0  and were able to perform read/write to nand flash without any errors.

I was able to go through all steps as mentioned by titus.

But i want to read and write to whole 512MB nand memory and confirm that whole nand chip is working fine.

Please suggest,

Hi,

Yes i tried as Titus suggested. But that write command  fills only 128 Kb starting from 0x100000 location. How to fill whole nand memory of 512MB.

Can i use below command to write into nand memory starting from 0 location like below ,

nand write 0x80000000 0 0x20000000

Will above command affects u-boot location ?


Below is Titus commands log,

U-Boot#

Hi Titus,

I want to know the u-boot build procedure to create image to boot it from NAND.

I am using u-boot  version u-boot-2015.07+gitAUTOINC+5922e09363 and followed the procedure in board/ti/ks2_evm/README to build MLO image

Supported image formats:
 - u-boot.bin: for loading and running u-boot.bin through Texas instruments
               code composure studio (CCS)
 - u-boot-spi.gph: gpimage for programming SPI NOR flash for SPI NOR boot
 - MLO: gpimage for programming AEMIF NAND flash for NAND boot

Build instructions:
===================
Examples for k2hk, for k2e and k2l just replace k2hk prefix accordingly.
Don't forget to add ARCH=arm and CROSS_COMPILE.

To build u-boot.bin
  >make k2hk_evm_defconfig
  >make u-boot-spi.gph

To build u-boot-spi.gph
  >make k2hk_evm_defconfig
  >make u-boot-spi.gph

To build MLO
  >make k2hk_evm_defconfig
  >make MLO

To build u-boot.bin
  >make k2hk_evm_defconfig
  >make u-boot.bin

AEMIF NAND Flash programming instructions
======================================
U-Boot image can be flashed to first 1024KB of the NAND flash using following
instructions:

1. Start CCS and run U-boot as described above.
2. Suspend Target. Select Run -> Suspend from top level menu
   CortexA15_1 (Free Running)"
3. Load MLO binary from build folder on to DDR address 0x87000000
   through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
   using CCS", but using address 0x87000000.
4. Free Run the target as described earlier (step 4) to get u-boot prompt
5. At the U-Boot console type following to setup u-boot environment variables.
   setenv filesize <size in hex of MLO rounded to hex 0x10000>
   run burn_uboot_nand
   Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
   to "ARM NAND Boot mode" as per instruction at
   processors.wiki.ti.com/.../*_Hardware_Setup.
6. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash.

I tried the exact way as described above, but it dint work.

Please guide,

Hi,

You have given me the step that has been used in u-boot version (uboot-keystone-2013.01) .In which below command  is been specified in Makefile to build the nand image.

make u-boot-nand.gph 

The u-boot version which i am using is u-boot-2015.07+gitAUTOINC+5922e09363 and they use differ command to build the u-boot for nand.

I refereed READ-ME file in path  board/ti/ks2_evm/README and followed up the same procedure to build the nand ,

To build MLO
  >make k2hk_evm_defconfig
  >make MLO

Supported image formats:
 - u-boot.bin: for loading and running u-boot.bin through Texas instruments
               code composure studio (CCS)
 - u-boot-spi.gph: gpimage for programming SPI NOR flash for SPI NOR boot
 - MLO: gpimage for programming AEMIF NAND flash for NAND boot

and i ported the  MLO image in nand as per the instruction but it dint work.

For booting through CCS,I followed up below commands

make clean
make k2hk_evm_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
make u-boot.bin ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

and able to load the u-boot binary and get the prompt,

Please suggest,

Hi,

I am getting this error when i compile using below command

 make u-boot-nand.gph ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
make: *** No rule to make target `u-boot-nand.gph'.  Stop.

We dont have NOR in our customize board so only way to boot u-boot is through NAND.

But i am not able to generate u-boot-nand.gph ,

I have downloaded this u-boot from ti software downloads site as you suggest in our previous post conversation.

Please guide,

Hi Titus,

Thanks for your reply,

I am able to compile u-boot for nand after adding script in Makefile. Have done some changes in script to compile and able to generate the image,

u-boot-nand.gph:        u-boot.bin
                $(objtree)/tools/mkimage -A $(ARCH) -T gpimage -C none \
                        -a $(CONFIG_SYS_TEXT_BASE) -e $(CONFIG_SYS_TEXT_BASE) \
                        -n U-Boot -d u-boot.bin gph-u-boot.bin
                @dd if=/dev/zero of=$(obj)zero.bin bs=8 count=1 2>/dev/null
                @cat $(obj)gph-u-boot.bin $(obj)zero.bin > $@
                @rm $(obj)zero.bin

Then followed below nand command to write image in nand and poweroff the board,

nand erase.part bootloader
nand write 0x82000000 bootloader 0x5cc30

But when i powered on , u-boot dint get booted up from nand. In DEVSTAT register, i have selected nand boot mode but still dint work.

I have no issues in  EVM u-boot booting.I compiled nand image in same manner and boot the image successfully. I compared the both image compiled from evm uboot and my latest u-boot -ver 2015 and it showed some difference.
